Synthesis and characterization of Pt, Pt–Fe/TiO2 cathode catalysts and its evaluation in microbial fuel cell

Year: 2016

Type: article

Abstract: In this present study TiO 2 supported metal catalysts (Pt/TiO 2 , Pt–Fe/TiO 2 ) were prepared by liquid phase photo deposition method. The prepared catalysts were characterized electrochemically. X-ray Diffractometer (XRD) results showed the presence of metal particle deposition on TiO 2 . HR-SEM and TEM results confirmed the nano size of the metal particles and their uniform dispersion on the surface of TiO 2 . Electrochemical methods such as cyclic Voltammetry, linear sweep Voltammetry were used to study the stability and oxygen reduction properties of the synthesized TiO 2 supported metal catalysts. The prepared catalysts were tested in Single Chamber Microbial Fuel Cell (SCMFC) with Escherichia coli of type DH5-α as bacterium. The power densities of Pt/TiO 2 and Pt–Fe/TiO 2 (110.5 and 136.8 mW/m 2 ) were found to be higher compared to that of Pt/C (77 mW/m 2 ) in MFC operation. The results visualized the better electro catalytic property for oxygen reduction in cathodic part of microbial fuel cell.
